SPRING-HINGE.

SPECIFICATION forming part of Letters Patent N 0. 69 5,124, dated March 11, 1902 Application filed October 1, 1900. Serial No. 31,676. (No model.)

To all whom, it may concern:

Be it known that we, ABRAHAM L. STUMP and FRANCIS BRUCKER, citizens of the United States, residing at Shelby, in the county of Richland and State of Ohio,have invented certain new and useful Improvements in Spring- Hinges, of which the following is a specification, reference beinghad to the accompanying drawings.

Our invention relates to double acting spring-hinges, and has for its object to pro vide certain improvements in spring-hinges of the general type illustrated and described in our former patents, No. 637,218, dated November 14, 1899, and No. 655,812, dated August 14, 1900. Such improvements relate to the pivotal support of the door, the devices for compressing the spring and regulating its action on the door, and the manner of mounting the spring. l

We accomplish the object of our invention as hereinafter specified and as illustrated in the accompanying drawings.

That which we regard as new will be set forth in the claims.

In the accompanying drawings, Figure 1 is a longitudinal vertical section of a door and j usting the door with reference to the spring.

Fig. 6 is a side elevation of the pivot of the door, the adj usting-plate, and the cross-head by which the action of the spring is transmitted to the door when the door is swung; and Fig. 7 is a section on line 7 7 of Fig. 6.

Referring to the drawings, 8 indicates the door, and 9 the door-jamb.

10 indicates a spring-barrel, consisting 01: a cylinder or suit-able casing, which is inserted horizontally in a suitable socket formed in the door-jamb, as shown in Fig. 1. The springbarrel 10 is provided at its front end with flanges 11.

12 indicates an extension of the spring-barrel, consisting of a hollow casing adapted to receive the outer end of the spring and the operating parts therefor. Said extension is provided with upper and lower flanges 13 14, which are fitted to the door-jamh and are secured thereto by screws 15 or in any other suitable man ner. The flanges 11 of the springloarrel 10 are secured to the flanges 13 14 by suitable means. The flanges 13 141 serve also as face-plates for the door-jamb.

The doorS is provided with a suitable socket in which is fitted a socket-plate 16, adapted to receive the extension 12 of the spring'barrel, said socket-plate being secured in position by screws 17 or other suitable means. A faceplate 18 is provided, which extends over the upper and lower portions of the socket'plate, as shown in Fig. 1, and is secured thereto by rivets or other means.

19 indicates a recess at the upper portion of the socket-plate 16, which is adapted to receive an adjusting-plate 20, arranged horizontally above the pivot 21 of the door. The pivot is best shown in Figs. 1 and 6. It is rigidly secured to the adjusting-plate 20 or formed integral therewith, so that as the pivot rotates the adjusting-plate 20 swings in a horizontal plane. The pivot 21 is fitted in a suitable sleeve or hearing 22, supported in the upper portion of the extension 12 of the spring-barrel, as shown in Fig. 1. The upper portion of the extension 12 is reinforced to provide a secure support for the sleeve 22 by a horizontal plate 23, as shown in Fig. l, which is secured to the upper portion of the extension 12, as shown. In the construction illustrated the reinforcing-plate 23 is formed integral with the upper portion of the extension 12, which is also formed integral with the flange 13, the lower portion of the extension 12 being formed integral with the flange 1i and being connected with the upper portion of said extension at the back and at the sides by a U-shaped plate 24, as shown in Figs. 3 and 1. The parts are secured together by screws or rivets passing through ears 25, carried by the extension 12 and plate 23, as shown in Fig. 1.

From the foregoing description it will be seen that the door is supported by the extension 12 and turns on the pivot-.21. The pivot is caused to-turn with the door by means of adjusting-screws 2627. (Best shown in Fig. 2.) Said screws pass through the face-plate 18 and the adjacent portion of the socketplate 16 and abut against the outer edge of the adjusting-plate 20, fitting into shallow recesses or countersunk portions, as shown in Fig. 2, so that as the door swings one or the other of said screws 26 or 27 bears against the edge of the adjusting-plate 20 and rocks the pivot 21 with the door. By adjusting the screws 26 27 the door may be adjusted to bring the face-plate Band 18 into line and occupy the proper position when at rest or to draw it close to the jamb. The lower end of the pivot 21 carries a cross-head 28, as best shown in Fig. 7. Said cross-head is fixedly secured to the pivot 21, so as to rock with it, and lies immediately below the sleeve 22, as shown in Fig.1. Said cross-head is provided with rounded ends 29 30, which form bearings, as will be hereinafter described.

31 indicates a spring which is arranged horizontally in the spring-barrel 10, its outer end projecting into the extension 12,as shown in Fig. 1. A bolt 32 extends through the spring 31. Said bolt passes through the plate 24, its head engaging said plate, as shown in Fig. l, and it carries a nut 33 opposite the inner end of the spring. Between the nut 33 and the spring is a guide-plate 34, which is of U shape and partially incloses the inner end of the spring. By rotating the bolt the nut may be adjusted with it, since the nut cannot turn, owing to the fact that it is of such size as to engage the spring-barrel if partially rotated. The tension of the spring may therefore be regulated at pleasure. The spring is compressed by the swinging of the door through the instrumentality of a sliding bar or plate 35, which is arranged horizontally in the spring-barrel and provided at its outer end with a flange 36, which extends down over the outer end of the springand is provided with a suitable hole through which the bolt 32 passes, as shown in Fig. 1. By this construction as the bar 35 slides back and forth in the spring-barrel the spring is compressed or relaxed, as the case may be. By the construction described the spring is compressed by pressure applied to its outer end, which moves the outer end of the spring inward. Consequently the compressing pressure acts to hold the flanges 13 14 against the door-jamb instead of tending to push said flanges away from said door-jamb, as is the case in devices of a generally similar character where the spring is compressed by pressure applied in an outward direction to its innerend. Furthermore, bycompressingthe spring by application of inward pressure, as above described, the general tendency is to hold the parts of the hinge together instead of to pull them apart, as is the case in oppositely-actin g springs. The spring is also prevented from flying out of its casing when the pressure is released thereon, as might happen if the pressure was applied in an outward direction, and the plate at the outer end of the extensioncasing becomes detached or dispensed with. The swinging of the door reciprocates said sliding bar 35 by means of arms 36 37, mounted on pivots 38 39,1'espectively, carried by said bar 35, said arms being pivoted near the inner end of said bar and extending toward the cross-head 28, as shown in Figs. 3 and 4. The outer ends of said arms are provided with concave sockets to receive the rounded ends 29 30 of the crosshead, as shown in Fig. 3. When in their normal position, as when the door is closed, as

shown in Fig. 3, the arms 36 37 lie at an acute angle to each other, their outer ends diverging and being in contact with the ends 29 30, respectively, of the cross head 28. When, however, the door is swung, as shown in Fig. 4, one of the ends, as 30, of the crosshead exerts a longitudinal pressure on the corresponding arm 37, forcing the sliding bar 35 inward and compressing the spring 31, so that when the door is released the resiliency of the spring serves to return it to its normal or closed position. When the door swings in the opposite direction, a similar operation takes place. The arms 36 37 cannot spread too far, because they are confined by the plate 24 and the spring-barrel. They are prevented from approaching each other too closely by a pin 40, which is secured in the upper portion of the extension 12 and the plate 23 and extends down between said arms, as shown in Figs. 3 and 4. Said pin, in conjunction with the spring-barrel, serves to keep the arms in proper position to engage the ends of the cross-head 28.

From the foregoing description it will be seen that the tension of the spring may be readily adjusted at pleasure, as all that it is.

necessary to do is to swing the door far enough to expose the end of the extension 12, when the bolt 32 may be rotated to adjust the nut 33 upon it and secure the desired adjustment of the spring. The position of the door with reference to the adjusting-plate 20 may also be regulated at pleasure by swinging the door far enough to expose the screws 26 27 and adjusting such screws with reference to the plate 20. V

41 42 indicate ornamental moldings which may be placed at each side of the flanges or face-plate 13 14.
